Gold-beating machinery

WILLIAM VINE, OF HARTFORD, CONNECTICUT.

GOLD-BEATING MACHINERY.

Specification of Letters Patent No. 8,945, dated May 11, 1852.

To all whom it may concern:

l Be it known that I, WILLIAM VINE, of the city of Hartford, county of Hartford, and State of Connecticut, have invented a new and useful Improvement in the Construction and Operation of Gold-Beating` Ma- Y chines for Beating Gold Leaf, Foil, &c.; and

I do hereby declare that the following is a full and eXact description of this my improved, automatica-l gold-beater, reference being had to the plan accompanying and forming part of this specification.

The nature' of my invention consists in the combination of a cam or its equivalent so constructed as to be of a double form and action, with a rod sliding through a cylinder which is provided with a pivot so that it is free to move horizontally, said rod giving the appropriate movement to the packet, and therobjectmof theinvention being to give to said packet motions in two directions with only one cam.

Plan No. 1 shows the cams and the mode `of operating with the rod sliding through gold tobe beaten on the block I. D trip `hammer cam. Ehelve of hammer. F ham-` mer head. Gr driving'pulleys, withs belt to pulley on the cam shaft, or it may be ik gearing wheels. `H weight and pulley,

U (or may be a spring) to cause the return or ,backward movement ofV the sliding rod, keeping it constantly to `follow the irregubeing operated on by the hammer, and by shifting one cam for another all the motions y are accomplished. This movement is caused backward and forward by and in conformity with the shape of the indentations on the peri hery of the cams, assisted by the weight or spring) to cause the backward movement of the rod to the same. The lateral or right and left movement is caused simultaneously by the cams being properly shaped on the side or disk to the required form. These two irregular shapes on the cams acting in concert I call the double action cams, both the shapes acting together on the end of the rod, C, passing through the cylinder, B, (which is also movable on a center pivot, allows all the movements to take place of the packet on the block, I, the ligure and form of the salne of course, being made and regulated by the proper and peculiar form of the indentations on the cams.

By this improvement in the construction and operation of a gold beating machine, all the inconveniences of the machinery around the block, (in other machines) is done away with, which is an important' matter in consequence of the difficulty of saving the waste gold, which in many of the parts of beating flies off in iine particles by the concussion of the blow of the hammer, and mixes with the machinery, causing a serious loss and waste.

This improvement is also important as to the economy of expense of construction, also answering better and all the purposes of the different machines in use.

What I claim as my invention and improvement, and desire to secure by Letters Patent, is

The double action adjustable differential cams, or their equivalent combined with the sliding rod and pivoted cylinder, in connection with other parts of gold beat-ing machinery substantially, in the manner and for the purpose as herein set forth and described.
